Preliminary test

At approximately 70°C a mechanical shock was observed. This did not influence the measurement. From 200°C upwards the weight of the sample decreased significantly. At 272°C the sample weight had decreased by 25%.

After the experiment no test item was observed in the sample container.

 

Main study

One minor and one major endothermic peak between 125°C and 175°C were observed. The extrapolated onset temperature of the minor peak was 149.39°C. This signal was most probably linked to the presence of an impurity or another crystallographic species. The extrapolated onset temperature of the major peak was 162.17°C. Both effects were most likely obtained due to melting.

To investigate the melting peaks between 125°C and 175°C a repeated heating cycle was applied in the Experiment 2. A closed sample container was applied to investigate the endothermic peak between 250°C and 325°C.

With the first heating the extrapolated onset temperature of the melting peak was 149.39°C. The extrapolated onset temperature of the second peak was 162.29°C.

During cooling no effects were observed which were due to crystallization of the test item (results are archived in the raw data).

During the second heating a glass transition was observed between 25°C and 50°C. The inflection point of the glass transition was 40.53°C. An exothermic peak was observed between 50°C and 125°C. The effect was obtained due to cold crystallization of the test item.

The extrapolated onset temperature of the first (minor) melting peak was 159.82°C. The peak maximum of the second (major) melting peak was 163.85°C. The extrapolated onset and the peak maximum were not used for calculating the melting temperature, since it was obtained by melting of non-original test item.

The melting temperature was determined as the average melting temperature obtained from experiment 1 (162.17°C) and experiment 2 (162.29°C).

Conclusions:
The melting temperature of Lowinox® 22IB46 was determined at 162°C (435K) using DSC.
Executive summary:

The purpose of the study was to determine the physico-chemical properties for Lowinox® 22IB46.

 

The melting temperature of the test item were determined using differential scanning calorimetry (DSC), in accordance with the following guidelines:
